Arctic weather patterns do not generally bring much precipitation. Definitely not as much as in the south where humidity from sub-tropical areas makes its way up and is dumped as snow when sufficiently north. Witness all those big snow storms that occur in New York city. A large proportion come from the south or south-west, very few from the north. So, keeping the runways clear is not a problem per say. Of course, the snow-clearing season is much longer, and the lack of precipitation is perhaps compensated by snowdrifts due to high winds. Operating costs are also higher due to the high cost of living and transportation, especially in places not connected by road to the south. There is a one-two week period in the summer of very active shipping where goods are delivered and stocked by each community, and this includes the fuel that goes into large tanks that will last until the following year). A little used airport that doubles as an emergency runway for trans-arctic flights to Asia would also require fuel storage. Don't know how long jet fuel can be kept in a tank and what sort of effect the wide variations in temperatures (from -50c to +30c) would have on some emergency-spare-fuel that sits in a tank for years before being needed. If that market were truly profitable, I suspect that the solution would be to develop/approve a twin with greater than 180 ETOPS. After all, if you can survive for more than half an hour on a single engine, whether you fly 180 or 240 minutes shouldn't make much of a difference, would it ?
